The MacDonald S-20 is a single-seat sport aircraft that was designed in the United States in the early 1970s and marketed for home building.[1]

The aircraft is a conventional, low-wing cantilever monoplane with fixed tailwheel undercarriage and an open cockpit.[2] Construction is of metal throughout, with a forward fuselage of welded steel tube construction, with the rear fuselage built up of aluminium bulkheads and longerons. The wings and tail are also of aluminium construction, and the entire aircraft is skinned in the same material. Pop rivets are used extensively to simplify construction.[2]

The S-20 designation was applied to the prototype (registration N106AB), while aircraft built from the plans were designated S-21.[2]
